The mechanism of astragaloside IV promoting sciatic nerve regeneration

2013-09-11
(Press-News.org) Astragaloside IV, the main component of the traditional Chinese medicine astragalus membra-naceus, has been shown to inhibit inflammation, oxidation, and apoptosis, and exerts immu-noregulatory effects. Xiaohong Zhang and colleagues from School of Pharmacutical Sciences, Jilin University investigated whether astragaloside IV could promote the repair of injured sciatic nerve. Denervated sciatic nerve of mice was subjected to anastomosis. The mice were intraperitoneally injected with 10, 5, 2.5 mg/kg astragaloside IV per day for 8 consecutive days. The researchers found that astragaloside IV contributed to sciatic nerve regeneration and functional recovery in mice. The mechanism underlying this effect may be associated with the upregulation of growth-associated protein-43 expression. These findings were published the Neural Regeneration Research (Vol. 8, No. 24, 2013).

Tiny diamonds to boost treatment of chemoresistant leukemia

2013-09-11
Singapore, 11 September 2013 – By binding multiple molecules of a common leukemia drug with nanodiamonds, scientists from the National University of Singapore (NUS) and University of California, Los Angeles (UCLA) managed to boost the delivery of the drug to leukemic cells and retain the drug within the cells to combat the cancer. This novel discovery, reported for the first time, addresses one of the major challenges in the treatment of leukemia where the cancer cells develop ways to pump drugs out of the body before they can do their job, particularly after they are ...

Map of galactic clouds where stars are born takes shape

2013-09-11
SYDNEY: A UNSW-led team of astronomers has begun to map the location of the most massive and mysterious objects in our galaxy – the giant gas clouds where new stars are born. Using a telescope at Coonabarabran that narrowly escaped devastation in a recent bushfire, the team identifies the galactic clouds of molecular gas - which can be up to 100 light years across - from the carbon monoxide they contain. "On Earth, carbon monoxide is poisonous – a silent killer. But in space, it is the second most abundant molecule and the easiest to see," says Professor Michael Burton, ...

New technology transforms research in viral biology

2013-09-11
Researchers at The Mount Sinai Medical Center have developed an innovative system to test how a virus interacts with cells in the body — to see, for example, what happens in lung cells when a deadly respiratory virus attacks them. In the journal Cell Host & Microbe, investigators say such a technique will not only speed basic research into viral biology, it will also help scientists improve vaccine production, generate novel antiviral compounds, and advance the development of viruses that attack cancer cells. "We have a powerful system in place today to investigate ...

Robots take over

2013-09-11
CORAL GABLES, FL (September 9, 2013) — Recently, the global financial market experienced a series of computer glitches that abruptly brought operations to a halt. One reason for these "flash freezes" may be the sudden emergence of mobs of ultrafast robots, which trade on the global markets and operate at speeds beyond human capability, thus overwhelming the system. The appearance of this "ultrafast machine ecology" is documented in a new study published on September 11 in Nature Scientific Reports. The findings suggest that for time scales less than one second, the financial ...

Rosemont, Ill. – The American Academy of Orthopaedic Surgeons (AAOS) today released a list of specific tests or procedures that are commonly ordered but not always necessary in orthopaedics as part of the Choosing Wisely® campaign, an initiative of the ABIM Foundation. The list identifies five targeted, evidence-based recommendations that can support conversations between patients and physicians about what care is really necessary. The Academy's list identified the following five recommendations: Avoid performing routine post-operative deep vein thrombosis ultrasonography ...

Biologists uncover mechanisms for cholera toxin's deadly effects

2013-09-11
Biologists at the University of California, San Diego have identified an underlying biochemical mechanism that helps make cholera toxin so deadly, often resulting in life-threating diarrhea that causes people to lose as much as half of their body fluids in a single day. Two groups of scientists working on fruit flies, mice and cultured human intestinal cells studied cholera toxin, produced by the highly infectious bacterium Vibrio cholerae. They discovered the toxin exerts some of its devastating effects by reducing the delivery of proteins to molecular junctions that ...

Hottest days in some parts of Europe have warmed 4 times more than the global average

2013-09-11
Some of the hottest days and coldest nights in parts of Europe have warmed more than four times the global average change since 1950, according to a new paper by researchers from the Grantham Research Institute on Climate Change and the Environment at the London School of Economics and Political Science and the University of Warwick, which is published today (11 September 2013) in the journal 'Environmental Research Letters'. The researchers translated observations of weather into observations of climate change using a gridded dataset of observations stretching back to ...
